1 vOnthe I f onvard movement .or noy'ementfi'o t-]1erightcofbracket 26the lower end 01 the vertical arm 34- of the bell-crank lever is swungto the right on the pivot 31 and causes the wire feeding plug 36 toengage the wire 23 which passes thereunder and the wire is thus carriedor fed along with it a pre determined distance limited by the length oftravel or forward stroke of the bracket.

'pivot 31 and the lower edge of the wire feeding block 36 is kicked upor raised,

.due to the fact that the pivot 35 is offcenter as respects the pivot31, so that said wide-feeding block is returned with the other partswithout, however, drawing the wire back with it. I prefer also toprovide a screw 53 extending through the Ushaped head of the bracket, asillustrated, and provided with the usual locking nut, said screw beingadapted to engage the bell-crank lever 32 to limit the swing or throwthereof on its pivot 31.

It is desirable after every forward stroke of the wire-feeder bracket 26and the consequent feeding forwardly of the wire 23 a predetermineddistance that the wire be clamped tightly while the bracket 1s beingreturned to its initial position and while the forward end of the wirehas been cut to form a pintle as will be described. 1 have accordinglyprovided a wire-clamping table 54: which is bolted or screwed to thetable 20 and which is provided with a case-hardened plate 55 countersunkin said table and secured thereto by suitable screws 56, allas shown inFig. 5. Said table is also provided with a perforated guiding extension57 through the perforation of which the wire 23 extends. Pivoted, as bythe pivot 58, to the pivot bearings 59 which are mounted. on the table20 is a wire-clamping lever 60 having a clamping head 61 adapted toengage and clamp the wire 23 firmly against the plate 55 of the clampingtable. The rear end of said lever 60 is forked as illustrated and haspivotally mounted between the arms of the fork a roller 61 engaging thecam periphery of a step cam 62 which is-mounted on or carried by theshaft 25. lVhen the shaft is rotated the lever 60 rocks on its pivot 58due to the cam action of the step cam 62 and the clamping head of saidlever intermittently clamps and unclamps the wire 23 in an obviousmanner.

63 indicates a wire-cutter support which is mounted on the tableadjacent the clamping table just described. Said support has mountedtherein a transversely extending guide bushing 64 which receivestherethrough the wire 23. 65 indicates a wire-cutting lever supported inan open bearing 66 on the table 20 the forward end of which lever isprovidedwith a head 67 pivoted, as at 68, to the side of the support 63and carrying a wire cutting blade 69. The rear end of said wire-cuttinglever 65 is provided with a hook 70 adapted to engage a lug or pin 71extending laterally from one side of a face cam 7 2 which is carried bythe shaft 25. F or every revolution of said face cam 72 the lug or pin71 strikes the hook 70 of the wire-cutting lever 65 and causes saidlever to rock on its pivot 68 thereby rotating the wire-cutting blade 69against the side of the support 63 a distance sufficiently to cut offthe wire at that point to form a pintle. The forward end of the spintle,if so desired, may be supported by any suitable form of supportingbushing 73 from which it may be removed in any dosirable manner.

Before operations are begun the end of the wire is brought over thewire-feeder through the guiding extension 57 of the clamping table, oversaid clamping table and through the transversely extending guide bushing64; of the wire-cutter support 60, and, if so desired, through thebushing 73. lVhen the shaft is rotated the wire is fed forwardly by thefeeder a predetermined distance, as previously described, and when thefeeder begins the return movement to its initial position thewire-clamping lever 60 is rocked on its pivot in the proper direction tobring the clamping head 61 thereof into clamping engagement with thewire. Immediately thereafter, and while the wire is clamped thewire-cutting lever 65 is rocked on its pivot to actuate the blade 69thereby causing the same to cut the wire to form a pintle, the bladethen being returned to in operative position, inasmuch as the lever 65immediately rocks in an opposite direction after the cutting operationhas been performed. After such cutting operation the lever 60 is rockedto release its clan'ipine; head from engagement with the wirewhereuponthe feeder begins its forward movement again and feeds the wireforwardly the same predetermined distance upon which the same sequenceof operations is performed.
